"The universe is currently estimated at roughly 13.8 billion years old, give or take 130 million years. In comparison, the solar system is only about 4.6 billion years old.
This estimate came from measuring the composition of matter and energy density in the universe. This allowed researchers to compute how fast the universe expanded in the past. With that knowledge, they could turn the clock back and extrapolate when the Big Bang happened. The time between then and now is the age of the universe"

I don't know what Last Thurdayism is. I don't think I am a troll, but if I was a troll then I hope that I would be one of those trolls that eat people, because eating people isn't completely acceptable if you're a person, but I think eating people would be delicious if I was a troll.
